Just to clarify: this is not misleading because of anything on NatureServe's end, but because EOL is not mapping different populations to their own pages, which seems like a reasonable policy in general.

See comments on bottom of ITIS page for this species: " The International Commission on Zoological Nomenclature (1998, Opinion 1894) ruled that Hydrochoerus is first available from Brisson, 1762, so it takes priority over Hydrochaeris Brünnich, 1772

I'm far from a whale expert, but the appearance and geographic location of this whale don't match Gray Whale, although they do match Southern Right Whale, which is how the image was originally tagged on Wikimedia Commons. I'm not clear how the image ended up tagged and Trusted on EOL as 2 quite distinct whale species.
